Delay is one of the most critical issues for construction projects and leads to huge losses in both developing and industrialized countries. The construction sector in Rwanda, a rapidly-developing nation, is no exception. Delays can be mitigated only once we have identify their primary causes, and these may not be the same in each region. This study aims to ascertain the main critical factors responsible for delays in building construction in Rwanda through an intensive literature review and questionnaire survey. A total of 40 delay causative factors were obtained from a literature review and were further classified into nine major categories. The questionnaire survey was distributed to about 80 respondents from clients, contractors, and consultants. From the list of 40 different factors, the top twelve most critical causes were identified as stoppage of work due to cash flow constraints, delay in approving design documents, confidentiality of physical plan, price fluctuations and delay in approving significant change, change orders, delay in performing inspections, Ineffective project planning, inadequate drawing details, unqualified labor, lack of materials on the market and dishonesty.

The purpose of this study was to review the conceptual framework of social constructionism and critical social constructionism in the research area of multi-cultural family homes, using a literature review. Fopp argued that social constructionism had an objectivation problem that only considered the actor side as a policy object; therefore he suggested a weaker social constructionist perspective with moderate relativism and the application of feminist epistemology to marginal life for maximizing objectivity. This article explores a conceptual framework for studying the reality of housing of multi-cultural families in Korea in the light of constructionist ideas and presents a review of empirical positivist data to support the framework. Based on results, using the social constructionist framework, five contexts (structural, institutional, organizational, operational, and intersubjective) were reviewed and ideas were suggested to develop an appropriate future situation for multi-cultural family homes. For a weaker social constructionist framework, three National Survey of Multi-Cultural Family Homes data sets were reviewed to determine the real condition of multi-cultural family homes. Further, from a feminist perspective, the empirical data of marginalized multi-cultural family homes were reviewed from the perspectives of gender inequality of decision making, cultural adaptation, and differentiation in housing related areas. In conclusion, two perspectives were useful for understanding multi-cultural family housing in Korea but must be compensated with substantial empirical data for a holistic approach.

The research is to identify important diffusion factors and their effects on green car diffusion process using system dynamics perspectives and a causal-loop analysis. Through a deep review on previous research, we have found the important factors of green car diffusion process. Price, driving range, network effect, recharge system, fuel cost had important facilitation on consumer attraction and green car diffusion. Based on the review, we have constructed a causal loop diagram explaining hybrid car diffusion process. We have found 3 important reinforcing loops in the causal loop diagram. Loop for learning & economies of scale(supply side), loop for network effect(consumer side), and loop for battery development(technology side) had most significant roles in the whole diffusion process. Through a deliberate analysis on the 3 causal loops, we have found meaningful results. First, there seems to exist a critical mass in the diffusion. Second, of the 3 loops, the battery technology had most significant role. Third, not consumer installed base but sales must be a standard to decide whether the critical mass is achieved or not. Based on these findings, several meaningful implications are suggested for the government and corporations related to the green car industries.

Purpose: Despite numerous evidence based preventive strategies of ventilator associated pneumonia (VAP) have been introduced, the incidence rate of VAP continues in an unacceptable range. The purposes of this review were to identify risk factors and diagnosis of VAP and to introduce current evidence based preventive strategies of VAP. Methods: A comprehensive literature search using keywords, including ventilator associated pneumonia were entered into a search engine. A number of highly pertinent papers relevant to the purpose of the review were identified. The papers that discussed specific preventive strategies of VAP were selected for analysis and inclusion in this review. Results: A number of evidence based preventive strategies that nurses can implement in their clinical practice to prevent VAP were identified. Such strategies include hand washing, use of protective gloves and gowns, oral care, stress ulcer prophylaxis, avoidance of unnecessary intubation, weaning protocol, sedation vacation, use of non-invasive ventilation, semi-recumbent position, continuous aspiration of subglottic secretions, and maintenance of proper endotracheal tube cuff pressure. Staff education is essential in preventing VAP. Conclusion: Preventive strategies of VAP should be applied to daily nursing care and each critical nurse should play a functional role in preventing VAP.

Objectives: This study was aimed to share the development process of the critical pathway (CP) for the treatment and management of stroke patients admitted to a Korean medicine hospital. Methods: A draft CP was prepared based on a review of relevant literature and medical records in the hospital, and its validity was reviewed by the in-hospital CP review committee. Each member evaluated all items in the CP on a 5-point Likert scale. Items with an average score of 3.5 or higher or an agreement rate of more than 80% were considered valid. In addition, free described opinions to improve the CP were also received from the review committee. Results: The horizontal axis of the CP was composed of a time domain, including 7 time points from hospitalization to discharge. The vertical axis was composed of 9 domains of medical practice. All items in the CP satisfied the validity criteria. The CP was revised, supplemented, and completed by reflecting the opinions of the committee. Conclusions: This CP will be taught to in-hospital users and will continue to be used with regular monitoring and a feedback plan. This study is expected to serve as a useful reference for standardizing the treatment process and delivering measures to improve the adequacy of Korean medicine treatment for stroke patients.

Chronic obstructive pulmonary disease (COPD) is an ambulatory care-sensitive condition, and effective treatment of outpatients can prevent worsening of the illness and hospitalization. Current COPD guidelines provide appropriate guidance for the diagnosis and treatment of patients with COPD. In fact, it has been shown that when appropriate guidance and treatment are performed, the morbidity and mortality rates of COPD patients are reduced. However, there is a gap between the clinical guidelines and the actual clinical treatment. Therefore, the Health Insurance Review and Assessment Service (HIRA) conducted an evaluation of the adequacy of COPD diagnosis and treatment using the Claims Database of HIRA. This review provides a summary of the COPD adequacy assessment results reported by the HIRA and some brief comments on the results.

This study critically appraised the accumulated articles based on the critical science perspective on Korea's home economics education. The 55 articles published from 1993 to 2011 were identified and placed into three categories: Critical science paradigm, practical problem-focused curriculum, and systems of action. The common result across categories was that some authors did not fully understand the concepts of practice, a practical problem-focused curriculum, the practical reasoning process, and the systems of action. A positive outcome of including a critical science perspective in the Korean national curriculum will be seen when systems supporting this perspective, such as those providing more specific information on a critical science perspective and the relevant textbook accreditation standards, are available. We present a proposal based on considerations of a national curriculum, teacher education, relevant philosophical perspectives, and classroom practice.

Critical mathematics education has developed in many directions and has a broad range of approaches. There will probably be many different ways of expressing critical mathematics education. The book, An Invitation to Critical Mathematics Education by Ole Skovsmose (2011) has elucidated critical mathematical education by discussing and reinterpreting its concerns and preoccupations. He reinterprets thoughts and arguments that have been taken for granted and premised in mathematics education, and also discusses unquestioned widespread notions by associating them with his projects or specific practices carried out by him and his colleagues. This review intoduced and examined his crucial notions of critical mathematics education, such as "Diversity of situations," "Students' foreground, Landscapes of investigation," "Mathemacy," and "Uncertainty." These notions will make you to meet his theories with his pratices and look back on something overlooked in mathematics education.

This study defines critical fashion designs and investigate its critical messages on fashion itself. The critical messages on fashion are categorized into two major issues of a fashion industry system and fashion consumer culture. This study contributes to the understanding of meaning and value for critical fashion messages that match critical art. As the research method, this study combines a literature review and case studies and the research scope focuses on cases that have appeared in fashion media since the 2000s when social critical messages in fashion began to emerge. The results of the study are as follows. Critical designers such as Viktor & Rolf, Elisa van Joolen, Issey Miyake, and Mary Ping have delivered messages challenging the nature of fashion industry system that criticize the cycle and limitation of a fashion system and pursues changes in perception of sustainability. The critical message on fashion consumer culture articulated by designers such as Alexander McQueen, Vivienne Westwood, Hussein Chalayan, and Ricarda Bigolin & Nella Themelios insist on the formation of community while delivering a critical message on social, political, and cultural problems that raise the mechanism of social awareness through fashion design.
